Talk:Schumann resonances

Schumann resonances was a good articles nominee, but did not meet the good article criteria at the time. There may be suggestions below for improving the article. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake.

Chimney ranking

This section refers to the African "chimney" and other chimneys, without explaining what a chimney is supposed to be. Wi thout an explanation, the section might as well be LLM gibberish. MrDemeanour (talk) 12:44, 17 July 2023 (UTC)[reply]

In this context, apparently continental "chimneys" refer to zones of increased lightning flash density^[1] . The highest lightning activity globally can be found in the Congo basin^[2] forming one of those zones.

But I could not find any other source than the aforementioned Williams2004 to use the term "chimney" for those zones. Kerel-fs (talk) 22:08, 29 January 2024 (UTC)[reply]

Broken link

The first reference (Schumann Resonance from NASA) is a broken link, it redirects to the plain NASA website. I don't know if maybe Internet Archive has a saved version of the original reference or not, but thought I'd make note of that here in case someone has the time to look into that, as I don't.

14.1 or 14.3?

You notice the image and the description have differing frequencies for the second order resonance? 2409:4073:200E:8B30:44C9:3771:2DD5:26B (talk) 10:11, 21 November 2023 (UTC)[reply]

Also the third frequency, which the text gives as 20.8 and the image shows as 20.3. Actually, the image has larger problems: the colors in the key were mixed up when the image was convereted from PNG to SVG, thus the frequencies are labeled wrongly. Do I remove the image? Notify the author? I'll leave that up to more experienced editors. Msittig (talk) 21:08, 19 March 2024 (UTC)[reply]

Those frequencies vary with sea level, weather, and solar activity. In other words: that 14.x Hz frequency is not a constant. tgeorgescu (talk) 22:02, 19 March 2024 (UTC)[reply]

The Montinel source says:

"The average fundamental mode of resonance is around 7.8 Hz, and the rest of modes are 14, 20, 26, 33, 39, and 45 Hz with slight diurnal variation."

However, the wiki article's /*Description*/ currently says they "appear as distinct peaks at extremely low frequencies around 7.83 Hz (fundamental), 14.3, 20.8, 27.3, and 33.8 Hz" yet cites that Montinel source (^[1]) despite those numbers being different.

Whatever numbers wikipedia uses should be matched to the source. If we have different sources, then lets put that there are different sources that give different numbers and have the specific numbers matched to the specific citation. Em3rgent0rdr (talk) 02:41, 2 May 2024 (UTC)[reply]
